Colour-magnitude diagram displaying the diverse sample of low-and planetary-mass objects observed as part of the ESO SupJup Survey. The pink, circular markers indicate the observed isolated brown dwarfs. The purple hexagons and dark purple diamonds depict the observed companions and their hosts, respectively. As a reference, the photometry of isolated brown dwarfs was obtained from the UltracoolSheet (http://bit.ly/UltracoolSheet) and is used to display late M, L and T dwarfs with increasingly darker marker shades. HR 3549B shows the J – H colour as its K-band magnitude has not been measured.
